That solution doesn't actually accomplish what the poster wanted: To stop the up/down arrow keys from changing the value in the numeric text box. It removes the up/down arrows but this is just cosmetic.
An earlier suggestion of unbinding the keydown event also winds up removing the ability to hit ENTER to complete the editing.
I liked another suggestion of using jQuery to set the step to 0. This seemed to work well in a jsFiddle. However in my implementation I can't get it to work. I put the "data-step=0" in various elements but the arrow keys still increment/decrement the numeric value. As you may notice I also tried removing the "role" attribute that said "role=spinnerbutton"
This numeric textbox is just the standard Kendo construction when I've marked my grid as "editable" i.e. I'm allowing in-cell editing here. There is no custom template. I tried to implement one but I'm not an expert on that and couldn't get it to work.
Attached is a screenshot of my markup. Any advice on the best approach here?
